为了验证基于网络编码的速率控制优化算法在接近真实的较大网络中的优化性能,将算法在OMNeT++平台上进行实现。通过对拥塞价格、物理流速率和路径成本在中间节点和信宿节点的连续优化,达到了网络流速率控制的目的。仿真结果表明,基于网络编码的速率控制优化算法在接近真实的较大网络中,传输速率同样能获得良好的收敛效果,而且还能提供较为稳定的网络吞吐量和较低的路径成本。
In order to verify optimal performance of the reference rate control optimization algorithm in a larger close to real network,this algorithm is implemented on OMNeT++ platform.It achieves the purpose of the network flow rate control by optimal congestion price,physical flow rate and path cost continuously on intermediate nodes and receiving nodes.The rate control optimization algorithm is verified in the simulation that not only transmission rate can obtain good convergence effect,but also it can provide more stable network throughput and lower path cost in a large close to real network.
